Aww ok. Her's is on 04.10.11 and I do not know what was used to unlock it. She's not as tech savvy so I do not want to do a tethered jailbreak because she would be lost if the phone ever turns off.
There is only 1 option to unlock hers was Gevey (turbo) sim. So, if you pop out hers micro sim tray, you will see the Gevy sim imposter in it.
